"It's great to be a mutant! It's the first time that I've played a mutant, so that was a great opportunity," he said.

"I've never played a billionaire playboy megalomaniac, so that's cool."

Kevin revealed the X-Men mutants are just like humans.

"They get jealous and they have hate and fear and they get drunk together," he said.

The 52-year-old, who didn't grow up with the Marvel comic books, felt under pressure to satisfy fans and hopes they will like his portrayal, despite the fact he has taken liberties with Sebastian's look.

"There certainly is a responsibility to fans of the comic books. I hope that they won't be too much disappointed with the fact that I don't look anything like Sebastian Shaw," he admitted.

"When I first read the script, I Googled him and saw this massive, Lou Ferrigno guy with a ponytail dressed like George Washington and I thought: 'I just don't know how I'm going to do that!' But that's not the look that Matthew wanted to go with."
